Abstract

The paper describes a complexes of soil micromycetes in Arctic island Izvestia TSIC as model polygon of human influence on micromycetes complexes in high Arctic. Soil samples from 7 groups of natural biocoenoses were studied by complex mycological methods including molecular analysis. The total of 54 micromycetes species were identified including 8 species of Zygomycetes (genera Cunninghamella, Mortierella, Mucor, Rhizopus and Umbelopsis). Most species belong to the anamorphic fungi. The genus Penicillium was dominated by the number of species (10 species), the genera Aspergillus, Cadophora and Cladosporium included 3 species. It should be noted that in addition to the filamentous microscopic fungi a significant part were represented by ascomycetous and basidiomycetous yeasts. The number of soil micromycetes on the island Izvestia TSIC ranged from 20 to 3500 CFU per 1 gram of soil. This index in the top soil layer of upland rock-moss-lichen polygonal plant communities ranged from 550 to 1500 CFU/g. The genera
